Harry Levy Attorney-Craig, Antonelli, Stewart & Hill ABSTRACT: An axle suspension, especially for the rear axle of motor vehicles in which two oppositely directed longitudinal guide members are pivotally connected with the wheel carrier serving as coupler member while a brake stator is pivotally supported on the forwardly extending guide member; the free ends of the longitudinal guide members are so pivotally connected at the vehicle superstructure that the straight lines extending through their joint axes intersect to the rear of the rear axle, and preferably at a point located to the rear thereof by at least one wheel diameter.
PATENTED APR 6197! 3573882 34 mvsmon FRIEDRICH H. VAN WINSEN ATTORNEYS AXLE SUSPENSION, ESPECIALLY FOR THE REAR AXLE OF MOTOR VEHICLES The present invention relates to an axle suspension in vehicles, especially for the rear axle of motor vehicles, which includes a longitudinal wheel guide member, preferably a lower longitudinal wheel guide member pivotally connected at the wheel carrier eccentrically to the wheel axle center and directed forwardly from the wheel carrier, and for the purpose of equalization of the brake pitching, a brake stator pivotally connected to the wheel carrier and supported on the longitudinal wheel guide member by means of a connecting member.
With a known axle suspension of this type having swinging half-axles pivoting about vehicle longitudinal axes, the brake stator is pivotallysupported in each case by way of a connecting member on the lower longitudinal guide member which is provided alone for'the support of a swinging half-axle in the thrust direction. Even though the brake pitching can be reduced or eliminated in such prior art construction, a starting equalization, i.e., an elimination of the starting dive movements of the vehicle occurring during the sudden starting of the vehicle, is not possible.
It is the aim of the present invention to eliminate this disadvantage either entirely or partly. Accordingly, the present invention essentially consists in that the wheel carrier is guided as coupler between'the aforementioned longitudinal guide member serving for the support of the brake stator and a further, preferably upper longitudinal guide member which is oppositely directed from the wheel carrier, and in that for the equalization of the starting dive the further longitudinal guide member is directed obliquely to the first-mentioned guide member in such a manner that, as viewed in side view of the vehicle, the center lines of the two longitudinal guide members extending through the respective joints thereof intersect at a point to the rear of the axle in the center spring position of the vehicle. Preferably, these center lines are each inclined rearwardly downwardly and intersect in a point which is located to the rear of the wheel center axis by at least one wheel diameter, preferably, however, is located to the rear of the wheel center axis'by a greater distance, and possibly may also be located at infinity with parallelly'extending center lines.
In contradistinction to the axle suspensions known heretofore in which either only the brake pitching or the start diving could be eliminated or one effect could be improved to the detriment of the other, both the brake pitching as well as the start diving canbe simultaneously avoided by the present invention.
Accordingly, it is an object of the present invention to pro vide an axle suspension, especially for the rear axle of motor vehicles which avoids by simple means the aforementioned shortcomings and drawbacks encountered in the prior art.
Another object-of the present invention resides in an axle suspension of the type described above which enables the simultaneous elimination of the pitching movements caused both by sudden decelerations and sudden accelerations of the vehicle.
These and further objects, features and advantages of the present invention will become more obvious from the following description when taken in connection with the accompanying drawing which shows, for purposes of illustration only, one embodiment of an axle suspension in accordance with the present invention, and wherein:
FIG. 1 is a schematic side elevational view of an axle suspension in accordance with the present invention, taken along line l-l of FIG. 2;
FIG. 2 is a plan view on the axle suspension of FIG. 1; and
FIG. 3 is a partial cross-sectional view taken along line 3-3 of FIG. 1 and illustrating, on an enlarged scale, the constructional details of the axle suspension of the present invention.
Referring now to the drawing wherein like reference numerals are used throughout the various views to designate like parts and more particularly to FIGS. 1 and 2, reference numeral l designates a conventional vehicle superstructure, for
joints l5 and 16 about the axis x -fi: \ivhich may be disposed either horizontally or also at an inclination to the horizontal. Thelower guide member 12 is connected with thewheel carrier 14 by means of a joint generally designated by reference numeral 17. For example, a joint pin 17a serves for this purpose which, as illustrated in FIG. 3, is securely anchored in thewheel carrier 14 and on which theinclined guide member 12 is supported, axially secured by means of roller bearings. Elastic or rubber bushings are preferably interposed in thejoints inclined guide member 12.
At one end thereof, theupper guide member 13 is pivotally connected at thewheel carrier 14 by a joint generally designated byreference numeral 18 which is spaced at a smaller distance from the wheel center axis than the joint 17 of thelower guide member 12 and thereby enables a low type of construction of the vehicle rear section, by means of a joint bolt orpin 18a and preferably under interposition of aringshaped rubber cushion 19; at its other end, theupper guide member 13 is pivotally connected at thevehicle superstructure 10 by means of aconventional joint 20. Theupper guide members 13, disposed mutually opposite on the two vehicle sides, can be connected with each other by a torsion rod serving as stabilizer which is disposed in the axis of thejoint 20 and which may simultaneously also form theguide members 13.
The vehicle is driven from a driving engine (not shown) arranged, for example, in the usual manner at the front end of the vehicle which drives, thewheel axle shafts 23, for example, by way of a cardan shaft and of a differential gear disposed between the rear wheels, thejoint shafts 21 as well as by means of the latter and suitably constructeddrive joints 22. Thewheel 25 as well as abrake drum 26 are rigidly connected in a conventional manner with theflange 24 of thewheel axle shaft 23. Thewheel carrier 14 is rotatably supported on thewheel axle shaft 23 by means of roller bearings in a manner to be described more fully hereinafter.
Thebrake shoes 27 are carried by abrake stator 28, whosehub 28a is axially inserted between theaxle shaft 23 and thewheel carrier 14 and is rotatably supported both relative to thewheel axle shaft 23 as also to thewheel carrier 14. For example, the tapered orconical roller bearings brake stator 28 and of thewheel carrier 14 on thewheel axle shaft 23. On the rear side of thewheel carrier 14, thehub 28a of thebrake stator 28 is connected with abrake support 28b thereof which carries thebrake shoes 27, for example, by means ofbolts 34 or the like. On the side opposite thebrake support 28b, thebrake stator 28 is provided with a forwardly extendingsupport arm 35 which is pivotally supported on thelower guide member 12 by means of aguide element 36.
As shown in FIG. 1, the straight line a-a between the joints l5 and 17 forming the guide centerline of thelower guide member 12 as well as the straight line b-b between thejoints upper guide member 13 are inclined rearwardly downwardly, and more particularly in such a manner that the point of intersection of the two straight lines is located to the rear of the rear axle and lower than the wheel center. The following is achieved thereby:
[f the vehicle is braked, then by reason of the mass inertia of the vehicle, the wheel 11 seeks to continue to rotate in the direction of arrow y (FIG. 1) and to take along thebrake stator 28 in this direction. Consequently, thesupport arm 35 exerts pressure by way of theguide element 36 upon thelower guide member 12 which is supported at 17 and thereby seeks to pull the vehicle superstructure l downwardly in the joints l5 and 16 which counteracts the lifting of the vehicle rear section and therewith the brake pitching.
If the vehicle is accelerated bya sudden starting, then in cooperation with the mass inertia of the vehicle, a reaction torque occurs in the rear axle drive which with the usual conventional constructions having forwardly supported longitudinal guide members, seeks to cause the wheel and superstructure to approach one another. By the arrangement according to the present invention of the lower and upper guide members l2 and 13 with a point of intersection of the straight lines 11-0 and b-b disposed to the rear of the rear axle, it is achieved, however, that alreadyin the center, starting position of the vehicle superstructure relative to the wheel a starting equalization is achieved which is I00 percent or even thereabove, if so desired.
The vehicle spring system can be constructed in any conventional, suitable manner. For example, for this purpose, coil springs, rubber springs, pneumatic springs or the like may be provided therefor which are interconnected between thelower guide member 12 and the vehicle superstructure.
While I have shown and described only one embodiment in accordance with the present invention, it is understood that the same is not limited thereto but is susceptible of numerous changes and modifications as known to a person skilled in the art, and I therefore do not wish to be limited to the details shown and described herein but intend to cover all such changes and modifications as are within the scope of such persons skilled in the art.
